Hard to say. I see hundreds iof kids dressed in Rey Mysterio Merchandise at every Live WWE Event. WWE makes $60 a pop off each Rey Mysterio Mask they sell. Now, let's talk about Rey Mysterio Necklaces, Bracelts, T-Shirts. I think WWE makes more Rey Mysterio Merchandise than they make for any other Wrestler and kids get their parents to buy that stuff for them. I'd say it's pretty close..

Rey Mysterio is very popular with the fans but is not very popular with a lot of other wrestlers and is not popular with vince McMahon and is on his 2nd strike with WWE and one more and he is out. they are hoping Rey's attitude will improve now that they've got him off steroids. but in the past few years Rey has made a lot of enemies with his behavior backstage.He has taunted other wrestlers, saying they can't do anything back to him because he is a WWE superstar and WWE will do anything to protect him and keep him safe and with the company because they make so much money from Mysterio's popularity. Rey slapped Brock Lesnar and a bunch of guys had to hold Lesnar back and Rey taunted Brock even more when he saw Brock was being held back and couldn't get to him. Big Show comlained about having to lose a match to Rey and when Rey foundout he confronted Big Show and called him names and spit on him and told Big Show if he layed a hand on him he would be fired and Big Show just walked off shaking his head. Rey pushed Rikishi so far that Rikishi snapped, grabbed Rey, put him down and sat on him and was squashing the life out of Rey until a bunch of other wrestlers grabbed Rikishi by his arms and pulled him off of Rey kicking and screaming. If Rey keeps on either vince is going to fire him or another wrestler is going to lose it and destroy Rey.
